As seen, entries with duplicate phone number, address or emails are allowed to be added into the company list. I believe this to be a bug as in reality, there would not be a case where different companies have duplicate details. Hence, the app should check for these inputs as duplicate entries as it is likely a mistake by the user, i.e. a legitimate user behaviour that should be prevented is allowed.

The same for the person list and event list.
